❓ Frequently Asked Questions (FAQ)

🔹 What is Base64 and why would I use it?

Base64 turns binary data into text. Web developers embed Base64 images directly into CSS/HTML to reduce HTTP requests.

🔹 Does this tool work offline?

Yes! After loading once, all conversions happen locally. No internet needed.

🔹 Why is there a 5MB file size limit?

Large images create huge Base64 strings that can freeze browsers. The limit keeps things smooth.

🔹 What if my browser doesn't support modern clipboard?

We have a fallback! If auto-copy fails, we show a manual copy box so you never lose your Base64 data.

🔹 How does Base64 validation work?

As you type, our tool checks if your Base64 string looks valid. You'll see a green check or red warning before even clicking convert.
